Color deviation on zoom?
Hi!
I'm starting with Capture One (9) and I immediately noticed strange and distracting behaviour. Please look at the photo, the inside rectangle pointed with arrows is the color I get when zoomed it (it's like it must look actually and how I get it after the export), outside photo - is what I see when the photo is zoomed out (messy yellowish-greenesh nasty cast). Very noticeable on the bottom line on the building. Colors differ much. Is this a bug? How to handle it or get rid of?
Please help
550D, raw

I fount a strange barrier when true colors turn yellowish ****. See, the first photo is zoomed in only a step more than second, but watch how colors are different!

Start by viewing the image at 100%.
Then zoom out and the effect you perceive will be those of compressing the size of the image by discarding pixels to make it fit.
What effect that may have on the colours will depend on how pixels are chosen for discard or retention and thus the balance of pixel colours that remain.
Bear in mind that HOW you see it may also vary depending on what surrounds the image on you monitor screen, the local ambient light (although you may have a fancy monitor that takes that into account?) and other lighting issues around you as you work.
Realistically, speaking as the owner of a 600D, anything created in very low ambient light at 3200 ISO with local artificial light influences is likely to be a very compromised set of data and my expectations from it would be very low indeed.
As you can see in your zoomed in image there is not really much colour detail but there is a lot of noise, just as one would expect.
HTH.

So this is incorrect resampling, yes?
How to avoid it than? I really can't rely on what I see the exported image is drasticly different.
Colour inaccuracy is the main reason to move out from Lightroom, and what do I see here? ☹️0 -

I'm not sure how you could decide what might correct colour sampling on a low exposure image shot at 3200 ISO based on a 6 or 7 years old consumer level digital camera file where the shot has been taken in dark conditions with some significantly difficult artificial light in the subject matter.
Perhaps others can share their experiences?

I don't know. I never saw anything like this in Lightroom despite it's awful in regards of colour 0 -

That might indicate something about the differences in processing between C1 and LR.0 -
It seems like the vignetting is fooling your perception of the color. They honestly look the same to me in the same reciter region. It could be the color and noise correction for the high ISO that is helping to fool your eye; you don't see it well until you zoom in a bit and it's not accurate until 100%.
The center region looks pretty much the same to me.0 -
It may also depend on your monitor. Here it's more noticeable

If you don't believe, this is side by side the original file in C1 and just exported from C1. IT'S THE SAME JPG! Not even RAW!

It's very different!

Sad to note, but 10.2.0.74 did not solve this nasty issue. I still have the same colour shift and it's distracting 😐 0
